DUI of Drugs – California Vehicle Code 23152(f)
Los Angeles DUI Lawyer Ron Hedding Explains DUID Charges
If you have been arrested for DUI of Drugs in Los Angeles, you are facing a rapidly growing category of DUI enforcement that is often misunderstood and aggressively prosecuted. Under California law, a DUI of Drugs charge does not require alcohol at all—instead, it focuses on whether any drug, whether legal or illegal, impaired your ability to safely operate a motor vehicle. This means that even if you were taking a prescribed medication exactly as directed by your doctor, you could still be arrested and charged if law enforcement believes that substance affected your driving.
California Vehicle Code 23152(f) specifically addresses driving under the influence of drugs and makes it unlawful to operate a vehicle while impaired by any drug. The key issue in these cases is not necessarily what you took—but whether it impacted your mental or physical abilities to a level that made you unsafe behind the wheel. In Los Angeles County, law enforcement has increasingly focused on drug-related DUI cases, especially with the rise of prescription medications, marijuana use, and other controlled substances. As a result, prosecutors are pursuing these cases more aggressively than ever. However, unlike alcohol-related DUIs, DUI of Drugs cases often rely on subjective observations and less precise testing methods, which can create opportunities for a strong legal defense when handled by an experienced DUI attorney like Ron Hedding.
What Is DUI of Drugs Under California Law?
Under California Vehicle Code 23152(f), it is illegal to drive while under the influence of any drug that impairs your ability to operate a vehicle safely.
A “drug” can include:
- Illegal substances (cocaine, methamphetamine, heroin)
- Prescription medications (painkillers, anti-anxiety medications, sleep aids)
- Over-the-counter medications (antihistamines, cold medicine)
- Marijuana (even if legally obtained)
The law does not distinguish between legal and illegal drugs—the focus is entirely on impairment.
How Police Determine Drug Impairment
Unlike alcohol-related DUI cases, there is no breathalyzer test for drugs. This makes DUI of Drugs cases much more subjective and often more defensible.
Law enforcement typically relies on:
- Officer observations (driving pattern, behavior)
- Field sobriety tests
- Statements made by the driver
- Blood or urine tests
- Drug Recognition Experts (DREs)
DRE officers are specially trained to identify signs of drug impairment, but their evaluations are based on interpretation—not hard science.
This creates a critical opportunity for defense.
DUI of Drugs Involving Prescription Medications
One of the fastest-growing areas of DUI enforcement involves lawfully prescribed medications.
You can be charged with a DUI of Drugs even if:
- You have a valid prescription
- You took the medication as directed
- You were not abusing the drug
However, these cases are often treated differently by prosecutors.
If it can be shown that:
- You did not intend to impair yourself
- You were unaware of the side effects
- Your driving was not dangerous
Then your attorney may be able to negotiate reduced charges or more favorable outcomes.
This is where presenting your story effectively becomes critical.
DUI of Drugs Involving Illegal Substances
If your case involves illegal drugs such as:
- Cocaine
- Methamphetamine
- Heroin
Prosecutors are far more likely to view the case as a public safety threat.
In these situations, the focus often shifts to:
- Whether your driving posed a danger
- Your prior record
- The circumstances of the stop
To counter this, your defense may include:
- Character evidence
- Evidence of non-dangerous driving
- Challenging the reliability of drug testing
These cases require a strategic and aggressive approach.
Key Defenses in DUI of Drugs Cases
DUI of Drugs cases are often more defensible than alcohol DUIs because of the lack of precise testing.
Common defense strategies include:
Lack of Impairment
Just because a drug is in your system does not mean you were impaired.
Lack of Knowledge
You may not have known the substance would affect your ability to drive.
Faulty Testing
Blood and urine tests can detect drugs long after their impairing effects have worn off.
Officer Subjectivity
Field sobriety tests and DRE evaluations are open to interpretation and can be challenged.
These defenses rely heavily on reasonableness and common sense, as well as a detailed review of the evidence.
Reviewing the Evidence Against You
Every DUI of Drugs case is unique and must be evaluated based on its specific facts.
When Ron Hedding reviews a case, the focus is on:

Once everything is on the table, a clear defense strategy can be developed.
